Application filed August 31, 1911. Serial No. 6%,9fi1.

To all whom it may concern:

Be it known that 1, Oscar: 1L. OWEN, a citizen of the United States, residing in Whitinsville, Worcester county, State of Massachusetts, have invented a new and useful Improvement in Scavengers for Spinning-Machines, set forth in the following specification.

The object of the invention is to make use of a traveling conveyor belt for scavenging spinning machines, having the least complication of structure and the fewest number of parts in its organization. The invention includes to this end various important features of construction, arrangement and operation whereby a traveling scavenger belt can be applied. to existing types of spinning machines with slight alteration, rendering them more efficient by the automatic removal of the broken ends of roving.

The invention is of special utility in connection with spinning machines used on short fiber or so-called Waste cotton, where brea-kages in the roving occur with frequency.

In the accompanying two sheets of drawings forming part of this specification,

Figure 1 is an end elevation of a spinning machine equipped with the new scavenger device, parts of the end frame upright thereof being broken out to show the interior arrangement;

Fig. 2 is a slightly enlarged transverse section of the machine of Fig. 1 taken in a plane at one end of the scavenger belt;

Fig. 3 is a side elevation of the same machine on a smaller scale than Fig. '1 with parts broken away;

Fig. 1 is a perspective detail of the overhanging end of the scavenger belt; and

Fig. 5 is a detail of the belt clearer brush.

The spinning machine taken .for illustration has a frame composed of three uprightsj marked 1, 2 and 3 respectively, carrying the longitudinal bolster rails 4: and the roller beams 5, the latter bearing the creel superstructure 6. The roller beams 5 on both sides of the frame are formed of angle iron, as shownin Figs. 1 and 2, with a vertical front flange and ahorizontal top flange upon which the roll stands 7 are mounted, the standards of these stands being of forwardly inclined or goose-neck with a series of forwardly projecting studs 9 spaced at intervals along its length, and at the forward ends of these studs there is mounted a rail 10 upon. which the row of thread-guides 11 is supported. In the present case the thread-guides are mounted in finger-heads 12 which are pivoted to an intermediate support 13, the latter being.

hinged to the rail 10 and normally sup ported in the position indicated in the drawings. The support 13 has a handle 13 appearing in Figs. 3 and 4c. The support or supports for the thread-guides, as thus mounted, are separated from the roller beam by a horizontally extending space of about three or four inches in width, which space is centralized with respect to the position of the delivery rolls above referred to and extends horizontally adjacent the upper front part of the roller beam for the full. length of the spinning machine, that is to say, from the first spindle adjacent the frame upright 1 to and through the upright 3 at the opposite end of the machine.

Power is applied to the machine at the drive pulley 14 mounted adjacent the end frame upright 1 on a longitudinal shaft 15 which carries and drives the spindle band drum 16 by "which the spindles 17 are rotated in their bolster rails 4: on both sides of the machine. The upright 1 is hollow and forms a housing for a gearing train marked 18 through which the power shaft by a connection, not shown, drives the several delivery rolls and also the supply drum 19 in the creel. The shaft 20 of'one of the gears of this train is extended through the wall of the housingin a boss 21, inwardly to a point adjacent the first spindle in the roll where it is provided with a worm 22 meshing with a worm-wheel 23 of a cr0ss-shaft 24:. This cross-shaft is j ournaled horizontally in two brackets 25, each of which is bolted to the inner side of the vertical front flanges of the roller beams 5, and extends at both ends somewhat beyond the brackets and beams where it carries the drive pulleys 26, the latter being thus located in the space in front of the roller beam above referred to and at one end of the latter and adjacent to the first spindle in the row. The pulley has a radius about equal to the depth of the roller beam flange and is thus adapted to support the scavenger belt 27 in a position slightly below the level of the row of thread-guides but above the supporting studs 9 by which the latter are carried. The bracket 25 also carries the support for a belt-guide pulley 28 shown in Fig. 3, which pulley is mounted with its axis on substantially the same level as that of the cross-shaft 24.

The scavenger belt 27 is of about the width of the space between the front of the roller beam and the rear face of the thread-guide supporting rail, and extends in a horizontal plane through such space and below the top thereof to a point somewhat beyond the end of the roller beam and the adjacent end frame upright 3, the latter being recessed as indicated at 3 in Fig. l to permit the belt to pass through and project beyond the end of the machine frame as shown in Fig. 3. At this point the belt is carried on a suitable guide such as the idle pulley 29, passing around the same and back to the drive pulley over a clearer brush 30, a take-up pulley 31 and the guide pulley 28 above referred to.

" The take-up 31 is adjustbly mounted on the intermediate frame upright and is adapted to vary the tension of the belt as desired. The clearer brush 30 which is separately shown in Fig. 5v is formed with bristles at two elevations, the shorter bristles being in the middle to engage the face of the belt, and the longer bristles being at the side to clear the edges of adhering fibers and the material of which the belt is made being of such degree of smoothness as to permit the ready dislodgment of the yarn by this means. The brush stock 32 in which the bristles are mounted is adjustably bolted to the end frame upright 3 immediately beneath the lower edge ofthe belt recess 3*, the adjustment being for the. purpose of taking up wear. The guide pulley 29 is mounted on a sleeve 33, ad-jjustably set-screwed upon a stud 34L securedv to the outer side of the upright 3 parallel with the roller beam, so that the pulley can be moved horizontally to accommodate the length of the belt. The position of the pulley projecting beyond the end of the machine frame-provides for the placing. of a box 35v directly beneath the end of the operating stretch of the scavenger belt to catch the droppingstherefrom. Such box can be mounted on. a shelf orupon the floor, or it can be attached: to the end frame as shown in the drawings. The rail 10 can,

if desired, be provided with an extension l0 following the contour of the belt'around the guide pulley 29 as indicated in Figs. 3 and 4, for the purpose of continuing the guiding efiect of the rail upon the belt beyond the end of the frame. Such extension is desirable for keeping the cotton on the belt from falling off at one side, as well as to guard the belt from accidental contact.

In the operation of the machine the reving passes from the creel through the rolls 8, thence through the thread-guides and thence to the travelers on the ring rail 36 in the usual manner. In the case of a break in the roving the broken end will fall downwardly as indicated in Fig. 2 and upon the top of the upper stretch of the conveyor belt 27 which is driven at a speed not exceeding the surface speed of the drawing rolls, being carried thereon and deposited in the box 35 at the end of the machine without conflict with the other unbroken rovings. The location of the upper stretch of the belt between the roller beam and the longitudinal supporting member of the threadguides keeps the roving from falling off of the edge of the belt, and at the same time forms a shelter for the spindle bands and other lower parts of the mechanism of the machine, protecting them against accumulations of fly. The mounting of the scavenger belt and its relation to the other parts is such that it. can be removed from the machine without unlacing, by removing the tension thereon and slipping it laterally over the thread-guide supporting rail.
